Introduction
PENTAGRAM horNET Wi-Fi USB Lite (P 6122-07) is a high-performance, easy-to-install 32-
bit wireless network adapter attached via USB. The adapter can be used in ad hoc mode to
establish peer-to-peer connections with other adapters for file sharing, or in infrastructure
mode to provide Internet access on home or office networks using an access point or a router.
PENTAGRAM horNET USB supports 802.11g connectivity with a maximum data rate of up to
54 Mbps! With a rich feature set, it can also interoperate with 802.11b (11 Mbps) products in
home or office environments, and with public hotspots. Regardless of the mode, your data
remain secure thanks to robust WPA encryption.

Authentication and Security
This tab provides wireless network security settings. The appearance of this tab depends on
the option selected in the Authentication Type field.
•
••
•Authentication Type: Open or Shared
Authentication Type: With the Open method, every wireless station can request
authentication. With Shared authentication, the station requesting authentication must
provide a secret key (which can be obtained from the network administrator) using
a secure channel (independent of the 802.11 wireless communications channel).
Encryption: Select None or WEP.
WEP Key#1...4: When you select WEP encryption or Shared authentication without
802.1x, you need to enter a correct WEP key.
•If a 64-bit WEP key is used, enter 10 hexadecimal characters or 5 ASCII characters.
•If a 128-bit WEP key is used, enter 26 hexadecimal characters or 13 ASCII
characters.
Show Password: Select this box if you do not want password characters to be replaced
with “*”.
Use 802.1x: Click this button to use IEEE 802.1x for authentication. IEEE 802.1x
supports full user authentication and control.
802.1x Setting: If IEEE 802.1x is enabled, click this button to open a dialog box with
IEEE 802.1x parameters.

•Authentication Type: LEAP
Authentication Type: LEAP (Light Extensible Authentication Protocol) is an EAP
authentication method used primarily on Cisco Aironet wireless networks. This protocol
encrypts transmitted data using dynamically generated WEP keys, and supports two-way
authentication.
Identity: Enter your identity for the LEAP authentication service.
Password: Enter your password for the LEAP authentication service.
Show Password: Select this box if you do not want password characters to be replaced
with “*”.
•
••
•Authentication Type: WPA, WPA-PSK, WPA2 or WPA2-PSK
Authentication Type: Select WPA, WPA-PSK, WPA2 or WPA2-PSK.
Encryption: Select the encryption method to be used.
•TKIP (Temporal Key Integrity Protocol) uses stronger encryption algorithms and
MIC (Message Integrity Check) to provide security against hackers.

horNET Wi-Fi USB Lite (P 6122-07)

•AES (Advanced Encryption System) uses symmetrical 128-bit data block
encryption.
WPA Preshared Key: Enter the WPA preshared key (WPA-PSK and WPA2-PSK only).
The key should be 8 to 32 characters in length.
802.1x Setting (WPA and WPA2 only): Click this button to open a dialog box with IEEE
802.1x parameters.
Show Password: Select this box if you do not want password characters to be replaced
with “*”.
•
••
•802.1x Setting dialog box
Authentication Type: Select the authentication method to be used.
•PEAP: PEAP (Protected Extensible Authentication Protocol) uses tunneling to carry
credentials between PEAP clients and the authentication server. PEAP can
authenticate wireless LAN clients by using server-side certificates only, which
simplifies the implementation and administration of a secure wireless network.
•TLS/Smart Card: Transport Layer Security uses certificates and two-way
client/network authentication. TLS is based on authentication using client-side and
server-side certificates, and can be used to dynamically generate user/session
based WEP keys to secure further communications between a wireless network
client and the access point.
•TTLS: Tunneled Transport Layer Security uses certificates and two-way client and
network authentication, and the data required for authentication are transferred
using an encrypted channel. Unlike EAP-TLS, EAP-TTLS requires only server-side
certificates.
•MD5-Challenge: This EAP authentication method provides basic EAP support. Only
one-way authentication is supported, therefore two-way client and network
authentication is not possible. This method can only be selected if Open or Shared
is selected as Authentication Type in the profile edit dialog.
Session Resumption: Select the session resumption method, i.e. Disabled,
Reauthenticate, Roaming, SameSsid or Always.
Identity: Enter your identity for the server.
Password: Enter your password for the server.
Use Client Certificate: Enable the client certificate for server authentication.
Protocol: Select the tunneling protocol from the list.
Identity: Enter your identity for the tunnel.
Password: Enter your password for the tunnel.

If you wish to use a CA (Certification Authority) server, click the CA Server tab.
Depending on the EAP method used, only the server or both server and client can be
authenticated and require a certificate. Server certificates enable clients to identify the
server, usually an authentication server or a RADIUS server. Most EAP methods require
a certificate issued by major or trusted certification authorities.
Use certificate chain: Select this option to enable the certification feature.
Certificate issuer: Select the server which acts as the certificate issuer.
Allow intermediate certificates: Select this option to allow the use of intermediate
certificates. These certificates must be located on the certification chain between the
server certificate and the server selected in Certificate Issuer.
Server name: Enter the name of the authentication server.
Two methods are available for server name matching:
•Server name must match exactly
•Domain name must end in specified name.
